Abstract
A method for learning an upwards friction coefficient of an engine clutch of a hybrid vehicle includes: after the engine clutch is engaged, disengaging, by a controller, the engine clutch which connects an engine with a motor or disconnects the engine from the motor; when the engine clutch is disengaged, comparing, by the controller, a temperature of the engine clutch with a threshold value; and when the temperature of the engine clutch is less than the threshold value, increasing, by the controller, a friction coefficient of the engine clutch up to a certain value.
Claims7
A method for learning an upwards friction coefficient of an engine clutch of a hybrid vehicle, comprising:
- after the engine clutch is engaged, disengaging, by a controller, the engine clutch which connects an engine with a motor or disconnects the engine from the motor;
- when the engine clutch is disengaged, comparing, by the controller, a temperature of the engine clutch with a threshold value;
- and
- when the temperature of the engine clutch is less than the threshold value, increasing, by the controller, a friction coefficient of the engine clutch up to a certain value.
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
- program instructions that, after an engine clutch is engaged, disengage the engine clutch which connects an engine with a motor or disconnects the engine from the motor;
- program instructions that, when the engine clutch is disengaged, compare a temperature of the engine clutch with a threshold value;
- and
- program instructions that, when the temperature of the engine clutch is less than the threshold value, increase a friction coefficient of the engine clutch up to a certain value.
